lately when i park my car i can hear a hissing or sizzling sound under the car. at first i thought it was just snow and water hitting my exhaust. its dry out and i still hear it. what could this sound be. almost like something is heating up then cooling down. cause it goes away after like 2-4 min. bad cat? thanks
Check your coolant level. Maybe the hissing sound is coming from under your hood? I had a coolant leak where my water hoses is suppose to be (near the fire wall). Every time I would turn off my car after a nice hot run, coolant would leak and burn sizzle.
nope no leaks no where
